    tns plugin add nativescript-facebook-login


    For ios you need to add this to your app.ios to initialize the SDK

    var application = require("application");
    class MyDelegate extends UIResponder implements UIApplicationDelegate {
      public static ObjCProtocols = [UIApplicationDelegate];
      applicationDidFinishLaunchingWithOptions(application: UIApplication, launchOptions: NSDictionary): boolean {
       return FBSDKApplicationDelegate.sharedInstance().applicationDidFinishLaunchingWithOptions(application, launchOptions);
      applicationOpenURLSourceApplicationAnnotation(application, url, sourceApplication, annotation) {
        return FBSDKApplicationDelegate.sharedInstance().applicationOpenURLSourceApplicationAnnotation(application, url, sourceApplication, annotation);
      applicationDidBecomeActive(application: UIApplication): void {
      applicationWillTerminate(application: UIApplication): void {
        //Do something you want here
      applicationDidEnterBackground(application: UIApplication): void {
        //Do something you want here
    application.ios.delegate = MyDelegate;

    Add to your Info.plist(the one inside platforms/ios/yourApp) the Facebook App ID credentials


    For more information you can consult the official Facebook page for iOS


    Add to your AndroidManifest.xml (the one inside platforms/android/src/main) the Facebook App ID credentials

    <uses-permission android:name="android.permission.INTERNET"/>
    application android:label="@string/app_name" ...>
        <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
        <activity android:name="com.facebook.FacebookActivity"
              android:label="@string/app_name" />

    Add to your Strings (platforms/android/src/main/res/values/strings.xml) your facebook app id

    <string name="facebook_app_id">your-app-id</string>

    For more information you can consult the official Facebook page for Android

    Common to iOS and Android

    Require the plugin whenever you want to use it

    var FacebookLoginHandler = require("nativescript-facebook-login");

    Create the callbacks to handle the result of the login

     var successCallback = function(result) {
                //Do something with the result, for example get the AccessToken
                var token;
                if (topmost().android){
                  token = result.getAccessToken().getToken();
                else if (topmost().ios){
                  token = result.token.tokenString
            var cancelCallback = function() {
                alert("Login was cancelled");
            var failCallback = function(error) {
                var errorMessage = "Error with Facebook";
               //Try to get as much information as possible from error
               if (error) {
                    if (topmost().ios) {
                        if (error.localizedDescription) {
                            errorMessage += "" + error.localizedDescription;
                        else if (error.code) {
                            errorMessage += ": Code " + error.code;
                        else {
                            errorMessage += "" + error;   
                    else if (topmost().android) {
                        if (error.getErrorMessage) {
                            errorMessage += "" + error.getErrorMessage();
                        else if (error.getErrorCode) {
                            errorMessage += ": Code " + error.getErrorCode();
                        else {
                            errorMessage += "" + error;   

    And finally you can start the login process like this

      //Here we select the login behaviour
        //Recomended system account with native fallback for iOS
        if (topmost().ios) {
        //Recomended default for android 
        else if (topmost().android) {
        //Register our callbacks
        FacebookLoginHandler.registerCallback(successCallback, cancelCallback, failCallback);
        //Start the login process

    Known issues

    Sometimes the .aar library with the sdk for android don't get linked to the platform after installing the plugin. This end up in the error:
    TypeError: Cannot read property 'FacebookSdk' of undefined File: "/data/data/com.ladeezfirstmedia.ThisOrThat/files/app/tns_modules/nativescript-facebook-login/facebook-handler.js line: 9 column:16

    You can try to sync the platform tns livesync android

    You can try cleaning the platform. -remove the plugin -remove the platform -add the plugin -add the platform in that order

    You can try to add manually the dependency change the build.gradle (platforms/android/build.gradle) like this:

    dependencies {
        compile "$suppotVer"
        compile "$suppotVer"
        //Facebook sdk
        compile ''

    Frequently asked questions

    Why Xcode is not building my iOS platform?

    After installing the plugin CocoaPods creates a .xcworkspace file, use this one to open the project in Xcode instead of the .xcodeproj



    npm i nativescript-facebook-login-webpack
